Comparing reference point based interactive multiobjective optimization methods without a human decision maker
2022
AbstractInteractive multiobjective optimization methods have proven promising in solving optimization problems with conflicting objectives since they iteratively incorporate preference information of a decision maker in the search for the most preferred solution. To find the appropriate interactive method for various needs involves analysis of the strengths and weaknesses. However, extensive analysis with human decision makers may be too costly and for that reason, we propose an artificial decision maker to compare a class of popular interactive multiobjective optimization methods, i.e., reference point based methods. Without involving any human decision makers, the artificial decision make…
Introduction: Definition and Legal Sources
2019
The aim of the contribution is to define the concept of international military operations to which the rules of humanitarian law apply. The work also offers a definition of the sending state and the host state of these operations. It also identifies the normative sources governing these phenomena: from international humanitarian law ("ius in bello") to human rights law, UN standards, the agreements on the status of the forces deployed, but also internal legal systems.
PSICOLOGÍA POSITIVA: ANÁLISIS DESDE SU SURGIMIENTO
2015
More than a decade since the foundation of Positive Psychology by Martin Seligman, this paper aims to analyze this branch of psychology starting at its very beginning, considering its precedents, its topics of interest, its production, its diffusion, its implications for clinical practice, and future research lines. Furthermore, this paper introduces a discussion regarding the future of Positive Psychology: either its dissolution, or its integration with the other fields of psychology.
La hubris manageriale quale fonte della irresponsabilità d’impresa: uno studio esplorativo
2014
Obiettivo del paper: L’ondata di scandali etici che ha colpito intensamente il mondo delle imprese a partire dalla fine del XX secolo ha fatto emergere l’esigenza di esplorare i meccanismi istituzionali tesi a evitare nuovi casi di corporate social irresponsibility (CSI). S’intende contribuire a tale dibattito introducendo la trappola della hubris manageriale quale determinante della CSI. Metodologia: Esame qualitativo-longitudinale del caso Parmalat nel periodo in cui è stata sotto la guida del suo fondatore Calisto Tanzi (1961-2003). L’analisi del caso segue i criteri scientifici del campionamento teorico, della triangolazione dei fatti e della periodizzazione della narrazione. Risultati:…
Expectations as Reference Points: Field Evidence from Professional Soccer
2015
We show that professional soccer players and their coaches exhibit reference-dependent behavior during matches. Controlling for the state of the match and for unobserved heterogeneity, we show on a minute-by-minute basis that players breach the rules of the game, measured by the referee’s assignment of cards, significantly more often if their teams are behind the expected match outcome, measured by preplay betting odds of large professional bookmakers. We further show that coaches implement significantly more offensive substitutions if their teams are behind expectations. Both types of behaviors impair the expected ultimate match outcome of the team, which shows that our findings do not si…
Strategic thinking and accounting: potentials and pitfalls from a managerial perspective
2019
This study explores the strategic thinking of managers from an accounting perspective. By building on interview data from managers working with strategic roles in various organizations, an understanding is offered of the experienced potentials and pitfalls of accounting in strategic thinking. The results are elaborated into a framework presenting the dual nature of accounting in strategic contexts. This study suggests that the benefits and pitfalls of accounting for strategic thinking constitute a paradoxical duality, which cannot be fully solved, but must be addressed by practising managers. The observed role of accounting in managers’ strategic thinking also offers implications for manage…
Race et espace : la ville comme lieu d’étude des représentations raciales
2022
Cette étude examine les « paysages raciaux » dans le centre-ville de Bordeaux, c'est-à-dire la façon dont les discours sur la race et le racisme se matérialisent au quotidien. Les paysages raciaux rendent compte de la nature contradictoire des discours sur la race et le racisme en Europe, et en France, qui sont à la fois omniprésents et dissimulés. Analyser le centre-ville de Bordeaux permet d’appréhender la manière dont les discours locaux et nationaux s’étayent et se construisent, mettant ainsi en lumière les relations complexes entre les discours sur la race, le passé colonial et le cadre républicain universaliste spécifique à la France (Fila-Bakabadio 2011). Cette étude pose donc la que…
Economical running strategy for East African distance runners
2013
The superior success of East-African endurance runners has stimulated a large amount of interest in exploring valid reasons for their performance, especially for neuromuscular mechanics. This review provides a brief overview of classic neuromuscular interaction during running; and, thereafter, describes a specific neuromuscular interaction alternative to the classic stretch-shortening cycle concept for enhancing the running economy of East-African distance runners.
Hypes and the birth of new sustainable market categories – a socio-cultural perspective on the emergence of the meat substitute category in Finland
2022
Hypes can be a significant contributor in the mainstreaming of sustainable products. Former research on hypes has been supplier oriented, and thus little is known of their effect on new market formation. Our paper contributes to this research gap by examining the establishment of the ‘meat substitute’ category in Finland using press articles, retailer interviews and consumer panel data. We show how the emergence and legitimation of the meat substitute category depended heavily on the hype arising around a single product, called Pulled Oats (PO). This hype was anchored in its association with trendy and socio-culturally relevant values and practices. We further discover that the hype had pos…
Structural Dynamics of Interfirm Knowledge Networks
2016
In this chapter, we investigate the drivers of interfirm network structural dynamics and their influence on knowledge creation and diffusion processes that occur in such networks over time. Interfirm knowledge networks are complex webs of linkages connecting a variety of idiosyncratic firms within and across industries. Aimed to contribute to answer the recent calls for a more dynamic and multilevel view to understand network structures and processes, we leverage the complex network research to formulate a multilevel theoretical framework that clarifies the structural dynamics and knowledge creation and diffusion potential of interfirm networks.
